The European Union has taken the lead to promote the management of coastal systems. Management strategies are implemented by the Water Framework Directive (WFD), the Marine Strategy Framework Directive (MSFD), as well as the recent Maritime Spatial Planning (MSP) Directive. Most EU directives have a strong focus on public participation; however, a recent review found that the actual ...

Coastal zones are the link between land and the sea and are unique areas, highly diverse in species, habitats and ecosystems. They are environmentally sensitive and economically valuable, with ecosystems rich in biodiversity also providing benefits such as protection from the elements, food and opportunities for the generation of renewable energy. They are also extremely important to human ...

The Gulf ecosystem is and has been under considerable stress, both naturally as well as due to anthropogenic activities associated with the exploitation of enormous oil and gas reserves in the region. This study focuses on developing and recommending an integrated strategic plan for the management of coastal resources in the Gulf region. An incremental approach has been recommended to minimise ...

Given the apparent difficulties of making policy-relevant decisions in the context of the sustainable development of coastal zones, a tri-phasic framework is proposed, whose aim is to formalise the ICZM (integrated coastal zone management) decision-making process. This formalisation is meant to promote shared responsibility, accountability and transparency, hence the justifiability of actions. ...

Modelling fine sediment dynamics, including transport, deposition and re-suspension, is very complex. This led to studies that validate the modelled suspended particulate matter (SPM) based on in-situ measurements. While in-situ measurements are often sparse in time and space, satellite measurements provide us with higher spatial and temporal resolution. This information can be used to validate ...

Results from a direct recharge experiment conducted in the field to investigate DOC and UVA254 attenuation rates during the direct injection of UF treated wastewater into a artificial coastal sandfill are presented in this paper. Approximately 500 m3 of ultra-filtered wastewater was injected into the saturated zone, over a period of 9 days. The movement of the plume was tracked over 80 days, ...

The main focus of the workshop will be the response of Arctic geophysical and ecosystem features to effects of Global Warming i.e., the decreasing sea ice cover, the destabilisation of permafrost systems and increased exposure of the coast to storms. Embedded in this context will be the important issue of reactions of human societies to these Arctic ...

The role of mangroves in protecting our coasts against natural hazards such as storms, tsunamis and coastal erosion has been widely promoted. But the supposed coastal protection services of mangroves have also been subject to debate. The Nature Conservancy and Wetlands International together with the University of Cambridge set out to map the current state of knowledge about the role of mangroves ...

This article critically examines the usefulness of scenarios in supporting environment-development planning, drawing from the experience of two differentiated case studies: integrated coastal zone in the Greek island of Rhodes (a country pilot project of the Coastal Area Management Programme implemented under the auspices of UNEP's Mediterranean Action Plan) and a more recent application on ...

An integrated indexes system for assessing water renewal of the northern coastal zone is developed; and rough sets theory is used to eliminate the redundancy in the indexes system. Then a variable fuzzy pattern recognition model is selected to evaluate the state of water renewal, which involves fuzzy information and interval numbers of classification standard values for evaluation. The indexes ...

BTs, PAHs, OCPs and PCBs were assessed in a mid‐latitude environment of the Patagonian coast, distant from important pollutant sources. Bioaccumulation processes through bottom sediment re‐suspension were suggested by BTs level found in surface sediment ( ...

Executive Summary This report provides information on the state of the environment in the coastal areas of Europe, and provides evidence of the need for a more integrated, long-term approach. Since 1995, concern about the state of Europe's coastline has led to a number of EU initiatives, which build on the concept of integrated coastal zone management (ICZM). ICZM attempts to balance the needs of ...

This paper aims at shedding new light on sustainability in coastal areas while defining a methodology for constructing social carrying capacity indicators. These indicators evaluate the levels and thresholds related to population growth pressures. From a Driver-Pressure-State-Impact-Response (DPSIR) framework, we centre on the Pressure and State processes and we follow a ...

Introduction One of the most dire impacts of anthropogenic climate change is a rise in the global sea level caused by the melting of glaciers and land-based ice caps, as well as a smaller increase from expansion due to the higher temperature of the water itself. Unlike some other predicted effects of climate change, this impact has already been observed for some time. Indeed, ...

The objectives of the DITTY project are to develop scientific bases for sustainable development of Southern European lagoons taking into account all the activities that affect the aquatic environment. Five sites have been identified ranging from the Ria Formosa (Portugal) at the entry to the Mediterranean Sea in the west, to the Gulf of Gera (Greece) in the Aegean archipelago in the east and ...

Considering rapid population growth and migration, higher accumulation of communities is noticed in coastal areas. This is especially true with the coastal areas of the Caspian Sea. In the present investigation coastal areas between Jouybar to Behshahr region is selected for their special geographical and ecological locations. Further, adverse impacts of human, agriculture and industrial ...

People and economies across the Caribbean are dependent on coastal ecosystems—including coral reefs, mangroves, and beaches. These ecosystems provide critical habitat to commercial fisheries, attract tourists from around the world, and protect coastal communities and infrastructure from the ravages of tropical storms. But despite their importance, these ecosystems are ...

Unsaturated-zone sediments and the chemistry of shallow groundwater underlying a small (8-km2) watershed were studied to identify the mechanisms responsible for anion storage within the Miocene Bridgeton Formation and weathered Coastal Plain deposits in southern New Jersey. Lower unsaturated-zone sediments and shallow groundwater samples were collected and concentrations of selected ions ...
